Things are moving along pretty quickly for newly engaged couple Janice Dickinson and Dr. Robert Gerner. The 57-year-old admits that their wedding is going to be a glamorous affair.

"I intend to make Rocky [Gerner's nickname] the happiest man in the world for the rest of his life," Dickinson tells Us Weekly. "I couldn't be happier right now. Oh! And our wedding is going to make Brad and Angelina's look like a trip to city hall!"

Dickinson and her psychopharmacology expert fiancé have only been dating for three months, but the former "America's Next Top Model" judge claims it was "love at first sight." Gerner proposed to her in the car before she dropped him off at LAX to attend a conference. They picked out her engagement ring together, which she flaunted at her engagement party over the weekend.

"I had a great time [at the party] and all my friends did too," Gerner says. "We complete each other -- our personalities really compliment each other."

In the past, Dickinson has been married three times: to Ron Levy, Simon Fields and Albert B. Gerston. Her last marriage lasted a year and ended in 1996.
